About SparxX Ltd

Enriching the present, the future, and beyond.

SparxX Ltd is a deep-tech company developing, designing, manufacturing, and marketing the Nucleus system — a next-generation hydrogen-on-demand technology that converts internal combustion and diesel engines into cleaner, more efficient engines, offering a scalable answer to the global fuel crisis.

The Nucleus supplements fuel by increasing octane and cetane levels, enhancing the vehicle's ability to burn all injected fuel completely. It cuts emissions by up to 70% or more, reduces petrol consumption by up to 45% or more, and diesel by up to 40% or more.

R&D commenced in 2008. The team successfully harnessed hydrogen through electrolysis — splitting water into hydrogen and oxygen. The first prototype was ready in 2010, followed by upgraded new generation models and rigorous testing across multiple countries to ensure quality, performance and stable results.

FAQ

Common Questions

Everything you need to know about the Nucleus technology, installation, and performance.

How does the Nucleus work?+
The Nucleus uses electrolysis to split water into Hydrogen and Oxygen. These gases are introduced into the intake system, improving combustion efficiency and reducing emissions — without modifying the engine.
Can it work on any engine?+
Yes. The Nucleus works on both petrol and diesel internal combustion engine, old or new. Any sector using an internal combustion engine is suitable.
Does it require engine modification?+
No modification is required. Only one 8mm insertion is made at the air filter. JPJ blanket approval is acquired for installation in all types of vehicle throughout the country.
How much fuel can I save?+
The Nucleus can improve your km/l mileage significantly. Typical results show up to 45% or more savings for petrol engines and up to 40% or more for diesel engines.
Will fuel savings decrease over time?+
No, as long as the Nucleus and the engine receive their scheduled maintenance. Savings only drop if the unit is neglected or the engine itself is already running poorly.
What's a baseline test, and how is it conducted?+
A baseline test records the vehicle's fuel performance before installation, using GPS fuel monitoring, or a digital flow meter. This is what verifies the savings figures.
Why is fuel testing conducted on the highway?+
Highway driving holds a constant speed in a controlled environment, giving the most accurate before-and-after comparison.
Why do I see less fuel savings in the city?+
Traffic, idling, and lower oxygen levels reduce efficiency in stop-start driving. The percentage saving stays consistent, but the absolute figure looks smaller in city conditions.
How does it reduce emissions?+
Hydrogen and oxygen improve combustion completeness, cutting CO, CO₂, and NOₓ. The only byproduct of the H2/O2 reaction itself is water.
How does it lower engine temperature?+
The oxygen produced converts back to water during combustion, drawing heat out of the cylinder. Lower running temperatures reduce the overheating that causes most breakdowns.
Does it extend oil-change intervals?+
Yes. Cleaner combustion leaves fewer carbon deposits, slowing oil degradation and component wear, which extends service intervals.
How much water does it consume?+
Very little — one litre of water lasts approximately 10,000 km.
Can NUCLEUS use tap water?+
No, currently only RO and distilled water is recommended for Nucleus.
What happens if you don't top up the water?+
The Nucleus can malfunction if not maintained properly. Regular topping up optimises Nucleus performance.
Will it drain the vehicle battery?+
No. The Nucleus requires only about 5 amps of current. The alternator continuously charges the battery and can produce up to 120 amps, so the draw is negligible.
What is the lifespan of Nucleus?+
The Nucleus is designed for a 10-year lifespan. Periodic maintenance every 6 months is recommended for longer lifespan.
Is it safe?+
Yes. Hydrogen is produced on-demand in tiny quantities and is never stored under pressure.
If NUCLEUS malfunctions, is it safe to operate?+
Yes. It's safe to keep driving, though we recommend shutting down the unit via its kill switch until it's serviced.
Will a malfunction shutdown affect my fuel savings?+
Not immediately. Carbon deposits take time to build back up in a clean engine, so savings hold for a while after shutdown.
What can go wrong with the NUCLEUS?+
Nucleus only needs regular maintenance to keep performing.
Is it safe to operate the engine if NUCLEUS is faulty?+
Yes. The engine runs normally regardless of the Nucleus's condition.
Can NUCLEUS cause any harm to the engine?+
No. As it requires no engine modification.
What happens if NUCLEUS keeps running while faulty?+
Some Nucleus components may be damaged, but the engine itself stays unaffected.
What's the turnaround time for a NUCLEUS repair?+
About two weeks.
Is the Nucleus patented?+
Yes. The Nucleus is a patented technology.
What certifications does it hold?+
Certified by SIRIM, Alam Sekitar, MINDEF/STRIDE, DBKL, MyHijau, JPJ, Millbrook (UK), and MYIPO.
What is the maintenance cycle?+
A periodic maintenance cycle of 6 months is required. Servicing takes approximately 1 hour and must be performed by a trained technician. The engine can remain operational during maintenance.
If NUCLEUS is this good, why isn't everyone using it?+
New technology takes time to displace entrenched habits or public adoption. Adoption is accelerating as field results and certifications build a track record.
